The accommodation looks like it does in the pics, and is 5 mins away from BTS Saphan Kwai. If you do want to try using the buses, there are lots of buses you can take to many destinations in Bangkok.
Lots of nice restaurants in the immediate area, a Big C shopping centre and two 7-11s in the area.
Negative: Could be a lot cleaner, found small bugs and a spider (and spiderweb) in the bathroom where the shower is. Dust is present in this room.
